To (LZ whom if? 771mg/ concern.-

Be it known that I, PATRICK M. Lnennn, a subject ol the King of Great Britain, residing at Berlin, in the county of Coos and State of New Hampshire, have invented certain new and usel'ul Improvements in Fire-Escapes, of which the following is a speciiication.

My invention relates to {irc-escapes, and has for its object to provide a device that can be easily and quickly attached to the window and one that is very eiiective in operation.

Another object of my invention is to provide a fire-escape that is very simple and cheap in construction and one that is under the perfect control of the user at all times.

A further object of my invention is to provide an auxiliary locking means, so that the bag or basket will be securely held while the person is getting in.

vWith these objects in view my invention consists of the novel construction and arrangement of parts hereinafter more fully described, pointed out in the claims, and shown in the accompanying drawings, in which- Figure 1 is a perspective view of the iireescape, showing it attached to the window. Fig. 2 is a crosssection through the brake, showing the auxiliary locking means. Fig. 3 is a perspective view of the brake-head.

Referring to the drawings, A indicates the supporting-arm, which is provided with a pulley A at its upper end and a cross-arm A2 at its lower end provided with pins adapted to engage the wall and prevent the arm from slipping. The arm is provided with a crossarin A3, adapted to rest on the window-sill, which prevents the arm from twisting, am havin@ a slot A4 formed midway its length provided with an opening leadinfT into said slot through one of the side walls which is provided with a thumb-screw A5, which engages the recess in the hooked arm B, which passes through the window and engages the inside wall and firmly holds the arm A in place.

Passing over the pulley is a copper rope C, one end carrying a ring to which is connected two short pieces C C2 of the same kind oi rope, which are connected to a hoop D, carrying the bag D. The rope C passes around the hoop and Ithrough an opening in the arm E, which is provided with a socket E at its l end provided with a transverse opening E2, through which the rope passes. A brake-arm E, provided with a head E', having a cut-out portion F2, is adapted to 'lit in said socket, the cut-out portion being held normali Y in alinernent with the opening E2 and in which the rope C rests. The arm I" is provided with a lever Etat its end, to which the other end of the rope is connected for stopping the bag at a predetermined time and by means of which the cut-out portion is turned in or out of alinement with the opening E2, so as to regulate the speed of the bag as desired.

To prevent all danger of the basket starting before the person 1s ready and to provide means for locking the bag up in a ready posi tion, I provide the socket with a screwthreaded opening E3, leading into the opening E2 and provided with a hand-screw E, which is adapted to force the rope up against the head F and securely hold the rope from passing through.

Having thus described my invention, what I clai as new, and desire to secure by Letters "tent of the United States, is-

1. In a device of the kind described, the

i combination with a supportingarm pro vided with apulley, of a rope passing over said pulley, a bag carried hy one end of said rope a brake mounted on said rope adjacent said bag, and a brake-lever connected to the other end of said rope for stopping the bag at a predetermined time, for the purpose descrilied.

2., In a device of the kind described, the eomlination with a supporting-arm, provided with a pulley, of a rope passing over said pnlley, a bag secu red to one end of said rope, a brake monnted on said rope connected to saizl bag, and a brake-arm connected to the other end. of said rope for stopping the bag at a predetermined time, for the purpose descrilzet 3. In a device-nf the kind described, the comlination w n a supporting-arm proviled with a pnl ey, of a rope passing over sai l pulley carrying a li ag at one end, a Lrake socket connected to said end adjacent the bag, an arm provided with a head fitting in said. socket, and a lever connected to said arm and to the other end of said rope for stopping the bag at a predetermined time, for the pirpose descrilef 4. In a device of the kind deseril'ed, the comlination with a sipporting-arm, provided with a pulley, of a rope passing over said pulley, a bag seci'red to one end of said rope, an arm provided with a socket secured IOO IIO

to said rope adjacent said ba a brake-head mounted 1n sai d socket provided with a leverarm connected to the end of said rope for stopping the bag at a predetermined time an( ocking means connected to said socket, for the purpose described.

5. In a device of the kind described, the Combination With a supporting-arm pro vided With a pulley, of a rope passing over said pulley carryinr a bag at one end, a brake-socket provi( ed with a transverse o ening, connectedy to said end adjacent t e bag through which the rope passes, an arm provided with a head having a cut-out portion arranged in said socket, a lever connected to a lever carried by said arm and to the end of the rope for stopping the bag at a predetermined time7 and locking means carried by said socket, for the purpose described.

6. In a device of the kind described the `combination with a supporting-arm provided With a pulley, of a rope passing over said pulley, a bag connected to one end of said rope and an arm connected. to said bag provided with a Socket at its end having a transverse opening formed therethrough, an arm provided with a head. at one end, mounted in said socket provided with a cutout portion, a lever secured to the end of said arm, the other end of said rope passing through the transverse opening in the socket having its end connected to the end of the lever for stoppingr the bag at a predetermined time for the purpose described.
